Hey, I'm Logan. I do a lot of maintenance/licensing work here on Commons, including reviewing files from external sources (such as Flickr and Panoramio) and renaming files that need to be renamed. I also transfer many files from local wikis, such as the English Wikipedia, so that they can be on Commons for everyone to use. :)
Feel free to drop me a note on my talk page if you have any questions and/or concerns. I have a more substantial user page over at the English Wikipedia, so you can find more details about my editing there.
Dome of the entrance hall (also known as the Staircase Hall), National Gallery, London (England). The National Gallery was founded in 1824 and has a collection of over 2,300 paintings from the mid-13th century to 1900. The present building in London's Trafalgar Square is the third to house the National Gallery, and was designed by William Wilkins from 1832–38. The Staircase Hall was designed by Sir John Taylor in 1884–7.
